主应力

Based on the Marc software package, a 3-dimensional finite element model was constructed to analyze the combined bend and torsion stress state of a bottom main drive spindle in the R2 roughing mill.

以某2250热轧带钢厂R2粗轧机承受较大载荷的下主传动轴为研究对象，采用Marc软件建立了该传动轴薄弱区段弯扭应力分析三维有限元模型。

The near band edge emission of GZO films has a blue shift with the increase of Ga doping concentration because of Burstein-Moss effect. Auger effect became obvious in Ga heavily doped ZnO which led to the quench of NBE emission.

研究表明近带边发射峰的移动主要是由Burstein-Moss效应引起；俄歇效应导致了近带边发射随Ga掺杂的增加产生猝灭现象；用微区应力模型解释了深能级跃迁发射带。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
